Sleeping posture and intraocular pressure.
INTRODUCTION This prospective observational case series aimed to determine whether the lateral decubitus position, which is commonly adopted during sleep, has an effect on intraocular pressure (IOP) in normal controls. METHODS Patients without glaucoma were recruited from those visiting outpatient clinics for non-glaucomatous conditions. The left eye of each patient was included. IOP was firs...
متن کاملPressure-Sensor System for Sleeping-Posture Classification
In this paper we present our research work on the classification of sleeping postures using pressure sensing. A densely pressure-sensor grid placed under the matrass is first used for the posture classification task that will serve next as a reference. Pressure data obtained from 21 subjects for 4 sleeping postures (supine, prone, left and right side) has been analysed to determine the optimal ...
متن کاملDetermination of Central Venous Pressure from Intraocular Pressure
Background: In many clinical situations, knowledge of central venous pressure (CVP) is important. Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery. Those with carotid artery or jugular venous diseases as we...
متن کاملEvaluation of the diurnal intraocular pressure fluctuations and blood pressure under dehydration due to fasting
Introduction: This study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. Methods: The intraocular pressures (IOP), body weights, as well as systolic and diastolic blood pressures (SBP, DBP) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...
متن کاملEffect of sleeping in a head-up position on intraocular pressure in patients with glaucoma.
PURPOSE To determine whether a 30-degree head-up sleeping position decreases nocturnal intraocular pressure (IOP) compared with lying flat in patients with glaucoma. DESIGN Prospective, nonrandomized comparative case series. PARTICIPANTS Seventeen eyes of 17 patients with glaucoma with controlled IOP and new disc hemorrhage. METHODS Patients with a new disc hemorrhage despite well-control...
